Other info. - This is one of the more common roses found in the state. It seems to prefer a shaded location with neighboring plants for support, but will grow fine in the sun and alone.
The plant is quite variable and Steyermark lists two varieties and five forms of the species, mostly based on leaf pubescence and flower color. I wont go into those here.
